The Study On Design Of Urban Wetland Park Based On Ecosystem Service Function

Ecosystem services(ES)refer to the benefits which people can derive from ecosystems.People's demand for high-quality life is growing,but due to the impact of urbanization,the global ecosystem services are deteriorating.The imbalance between the ES supply capacity of urban green space and urban development is concerned.As an important part of urban green space,urban wetland park bears a variety of ES functions and plays an important role in solving the problems brought by urbanization.Urban wetland park has become popular in recent years,but how to improve the ES capacity of the park to meet the needs of urban development is an urgent problem to be solved.This paper adopts the research method combining theory and practice.Firstly,this paper reviews the research progress of urban wetland park and summarizes the problems.Secondly,it sorts out the relevant theories of ES.Specifically,the functional contents of ES in urban wetland park are defined in four aspects: supply,support,regulation and culture.Then,it analyzes the functional coupling between urban wetland park and ES with the equivalent factor method,and takes Xiamen as an example to study the ES value gradient of urban wetland park,based on which the corresponding promotion design strategy is given.Finally,this paper proposes a research method of urban wetland park design based on ecosystem service function and applies it to the design of Jiuxikou Urban Wetland Park in Xiamen,aiming at coupling the ecosystem services function of urban wetland park with urban development needs and improving human welfare.
